Calorifier

with PICV control

Function

This calorifier allows room temperature to be controlled using a room controller connected to the PICV actuator. To avoid cold air being blown into the room, when fresh air is taken from outside, a timer can be inserted to delay the startup of the fan. The control can either be modulating or On/Off depending on the system layout.
